ABSTRACT:
A cable connector for supporting and retaining electrical conductors or cables in an opening of an electrical junction box or the like. The connector is comprised of a hollow tubular body with a saddle-shaped compound concave flange at one end and longitudinally extending folds or corrugations in opposing sides of the tubular body at the other end. The connector is formed of a readily deformable metal so as to allow the hollow tubular body to be compressed around a cable passed axially through it. The two radii dimensions of the compound concave flange are chosen such that upon compression of the corrugated section the flange is deformed into a flat, planar shape which abuts against the inside wall of the electrical box. Compression of the corrugated end also results in the centermost corrugation being forced outward so as to form an opposing abutment to the flange. Inwardly projecting dimples or elongated cleats on the opposing planar surfaces of the corrugated end enhance the frictional engagement of the connector with the cable.
